mounted to swing with respect to the bearnected to the said bearing at one end and is pivoted or hinged to the `frame at the other. The bracket consists of a portion 24 having reariend an npstanding cross head25, and having a lug 26 extending inwardly or rearwardly from the plate at Eits junction with the cross head 25. The plate 24, the

cross head, and the lug are integral and lug is received between the bearing 4 and sTots'l-,i "the lugs i"and through the bearing 28 andthe-endsofthe'bolt are engaged by nuts 32"o"u'tside-r of vthe lugs. Each end ,of the bolt has an opening outside of the nut and on;Y end of a coil spring 33 is connected with each' of the openings,k the other-end ofv y,the springfbeing connected to a pin 34 on` the innermost end. member of the frame 10.

V'sp .rings '33 act normally to move the ameIO' yand theparts which it supports utwardly'or forwardly and since the frame cannot move longitudinally of the crank shaft because of the sleeves 13 and 14, the

cranky shaft Vcarried withthe frame when the-v frame is moved.

' evel |gear wheels to be later described in detail "and indicated generally-by the reference pliaracters 35 and 3 6 are secured on the respective s'tub shafts 21 and 22 between the said members of the frame 10 and those ofthe'frame 2 3, and a third bevel'gear 37 is"r joiirnaled onV the upper end member of the-'frame' 23. Itwill be noticed frbm an inspection of'Fig.` 4 that a set screw 38 is Ifp asls'g'ed through the center of the bevel gear 3 J l Y j and engages an internally threaded boss 39in'the-upper vface of the upper end niember"j`b f"`theframe 2 3. lA cross head comprisi-iiga body 40k and arms 41 is connected to the: bevel gear `3"?, the body of the cross head being arranged on the outer face of the beyel gear, and the said body is secured to 1511.6.' 56361 Gef by S919 SCl-HS`"4t2-y bevel gear 37 and at the set screw SSad' a' feuiyrerboed Washer 4.3" isi held. in the Craving; the Said Srvpassilg throve theV washer.; and head of the "setfscrew @halls th@ YCQSS 'hal 1s rigidly @meestal with the bevel gear the arms eiten'dfinop `osite direetionsi approximately transverse to -fthe ing 4, on a bracket which is rigidly cork of bolts 2'?" whichY yend and a flexible member 44 is connected vto each arm, each of the said members being connected to an eye 41a engaging the opening of the adjacent arm. i The tlexible members 44 extendi rear? wardly beneath the hood to a pulley 45 which is journaled on the frame of the vehicle adjacent to the foot board thereofan'l bellow the foot board7 and each flexible member then passes upwardly from the pulley over a second pulley 46 which is joiirnaled in a slot in lthe foot hoard.'r A handle ,4 7 is secured to each flexible member onthe upper face of the footboard the handles normally restinapositon shown in Figs. 1 and 2 vposition'to begrasped by the driver tov operate the 'starting mechanism. V

will beevident 'that when traction is made onthe flexible members they will be drawn rearwardly and will the up` per'end of the frame, 2 3 rearwardly. Since this frame is connected to the frame l0 by the stub shafts 21 and 22 the frame 10 and the crank shaft 3 will also vbe moved rearwardly to cause theclutch sections and 6 to" engage each other.

"'It will be 'nbticedfro'm an inspection of.

Figs. and 6 especially rthat eachv bevel gear l1 andv is a mutilatedgear having teeth approximately ,only over 1809 of its perip'hery.. Each of the bevel gears .35 and 36 hastwo series of bevel gear teeth, the series having vunequal radii. The bevel gear 35- has an'inner series :35e of teeth and an outer series 35h, while the bevel gear 36 has an inner series 36"* and an outerv series 361. The series 35h and 36b of teeth mesh with the teeth of the bevel gear 37 while the teeth of series 3.52l and 36a of thebevel gears 11 and l2.

The operation of the improved starter is as follows; rIfhe operator grasps the handles 47 and draws the tlexible member rear wardly. 4'. lhis operation swings ,the upper end of the frame 23, which may be termed a resten rearwardly, moving the Shaft 3 rearwardly and causing the clutch sections 2 to mesh. llhe operator now imparts an oscillating movement to the cross head 41-432 by movingthe handles forwardly and rearwardly in' alI ernatiom that is, with a see-saw 'movement. v Whenever the cross head iseelated infths mannerythe eem" wheels 35 and 36 will be oscillatedin'oppo- Site directions, and, theV gear will impart: oscillating mOi/ement to the bevel gears 11 and' l2 in opposite directions.
